IMPROVEMENT IN TUCKERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 184,500, dated November 21, 1876; application filed July 15, 1876.

To all whom it may concern Be it known that I, ALoNzo W. BROWN, of Ogden City, in the county of Weber and Territory of Utah, have invented a new and Improved Self-Folding Tucker for Sewing-Machines, ofwhich the following isa specification:

My invention consists of a tuck folding and gaging machine, in which the contrivance is such that the tuck is gaged by the previouslyformed tuck, and there is another gage to regulate the width of the tucks, and a guardplate to prevent displacement of one of the folders by the work.

Figure 1 is a top view of my improved tucker. Fig. 2 is a sectional elevation taken on line 3 3 Fig. 1. Fig. 3 is a transverse section taken on line 00 m, Fig. 2.

Similar letters of reference indicate corresponding parts.

A is a U-shaped plate, of metal, arranged horizontally at right angles to, in front of, and at the left hand of, the presser-foot B, and attached to it at the rear of the upper side, near the end, so that the lower side rests a little above the plate of the machine, and the end of the lower part is provided with the hornguide 0, over which the cloth runs to make one fold of the tuck.

D is a tuck-folder, which attaches to the sewing-machine plate, at the right-hand side of the foot, by the ordinary clamp-screw E, and projects into the space between the upper and lower parts of the plate A, and has the horn-guide F, over which the cloth runs to make the other fold of the tuck.

On the top of plate A is the gage G, which is adjustably attached thereto by the thumbscrew H, for gaging the tucks, by running under the last tuck I, against the seam by which it is fastened, thus insuring parallel tucks.

The plate A is attached to the presser B by an upwardly-inclined piece, J, which supports the tucker, so that it does not interfere with the action of the presser on the feed-plate.

L is a plate to keep the plate D from being shifted out of position. It lies under plate D, and is fastened by the same clamp-screw, and also has another fastening by the hooked arm M taking in the hole of the slide-plate O at N, or any other; and the plate has a stud at P, which, together with the binding-screw, prevents the plate from shifting out of line.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of the plate A, arranged in U shape and attached to the presser, and having the horn-guide O, the folder D, having the horn-guide F, and the adjusting-guide G, substantially as specified.

2. The stay-plate, having stud P and hooked arm M, in combination with the plate D, substantially as specified.

A. W. BROWN.
